Neduntheevu or Nedunthivu is an island in the Palk Strait, northern Sri Lanka. This island is named as Delft in the Admiralty Chart unlike the other islands, whose names are Tamil. The island's area is 50 km2 and it is roughly oval-shaped. Its length is 8 km and its maximum width about 6 km.
Neduntheevu is a flat island surrounded by shallow waters and beaches of coral chunks and sand. It is home to a small population of Tamil people, mostly living in quiet compounds close to the northern coast. The vegetation is of a semi-arid tropical type, with palmyra palms, dry shrubs and grasses that grow on the pale grey porous coralline soil. Papayas and bananas grow close to the local people's homes. In the western coast of the island there are remains of a 1000-year-old temple built by the Chola Dynasty, as well as the ruins of a Dutch colonial fort. The water is slightly brackish, and it is taken from shallow wells using buckets made from palmyra palm leaves. A naval battle was fought off the coast of the island in 2008 during the Sri-Lankan Civil War. There are feral ponies on the island, descendants of forebears abandoned there in the Dutch period.
The island was named after the Dutch city of Delft by Rijckloff van Goens. He named the eight most important islands after Dutch cities.
Delft Island Fort
Delft Island Fort are ruins of a fort located on the island of Neduntheevu in the Palk Strait in northern Sri Lanka.
Traditionally attributed to the Karaiyar king Meekaman, the fort was probably built by the Portuguese. Later, it was taken over by Dutch, who built a barrack nearby. The island was known to the Portuguese as Ilha das Vacas ("Island of the Cows"), was renamed by the Dutch as Delft Island.
The fort was constructed out of limestone and coral. Though now in ruins, Ralph Henry Bassett describes the fort as a "very strongly fortified fort" in his book Romantic Ceylon: Its History, Legend, and Story.
